The force applied is 47.3 N
Explanation:
First of all, we start by calculating the acceleration of Hailey, which is given by
where:
v = 3.5 m/s is the final velocity
u = 2 m/s is the initial velocity
t = 2 s is the time elapsed
Substituting, we find the acceleration:
Now we can find the force applied by using Newton's second law:
where
F is the force applied
m = 63 kg is the mass of Hailey+the skate
is the acceleration
Substituting, we find the force:

Sand is the largest particle that can generally be carried by the wind.
Answer: Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. ... For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection
